C.A process where if two things are equal, one can be put in the place of the other and nothing will change. D.Terms that have identical variable parts. Question 3-Simplify the following expression. 2x - 2y + 5z - 2x - y + 3z A.x - 3y + 8z B.2x - 2y + 8z C.3y + 8z D.-3y + 8z Question 4 Part 1: Write an expression for the following real-world situation. Katie is moving to a new house. Small boxes hold 15 pounds each and medium boxes hold 25 pounds each. Write an expression for the total weight in the moving van if Katie uses "s" small boxes and "m" medium boxes. Part 2: Write a real-world situation of your own and a VARIABLE expression to go with it.

Answers:x - 3y if x = 3 and y = -2. 3-3(-2)=3+6 =9 answer D Question 2-Choose the best definition for the following phrase: like terms answer C.A process where if two things are equal, one can be put in the place of the other and nothing will change. 2x - 2y + 5z - 2x - y + 3z=(2x-2x) +(-2y-y)+(5z+3z) =-3y+8z answer D Katie is moving to a new house. Small boxes hold 15 pounds each and medium boxes hold 25 pounds each. Write an expression for the total weight in the moving van if Katie uses "s" small boxes and "m" medium boxes. s=Small boxes m=medium boxes T= total weight in pounds T=15s+25m
